Black silicon: Substrate for laser 3D micro/nano-polymerization [PDF]

open access: yes, 2013
We demonstrate that black silicon (b-Si) made by dry plasma etching is a promising substrate for laser three-dimensional (3D) micro/nano-polymerization. High aspect ratio Si-needles, working as sacrificial support structures, have flexibility required to

Shaping of molecular weight distribution using b-spline based predictive probability density function control [PDF]

open access: yes, 2004
Issues of modelling and control of molecular weight distributions (MWDs) of polymerization products have been studied under the recently developed framework of stochastic distribution control, where the purpose is to design the required control inputs ...

"Relationship between microstructure and properties of chlorinated butyl rubber"

open access: yesHecheng xiangjiao gongye, 2023
Several chlorinated butyl rubbers (CIIR) with different microstructures were selected to study the effects of microstructure and calcium stearate content on their vulcanization characteristics, physical and mechanical properties and heat aging resistance.

Polymerization of Cycloolefines

open access: yesKobunshi Kagaku, 1969
1, 3-シクロオクタジエソ (1, 3-COD) と液体亜硫酸 (SO2) との共重合について検討した。1, 3-CODはAgNO3, H2O2などの添加によりSO2と共重合し, DMF, DMSOおよびSO2に可溶な1: 1組成のポリスルポソを与える。共役二重結合へのSO2の付加は主に1, 2-付加であろうと推定した。AgNO3を触媒とし, 過剰のSO2中で重合を行なった場合共重合初速度はAgNO3初濃度の1/2乗に比例し (0℃), 活性化エネルギーは約8.5kcal/mol (-10-+15℃) であった。重合初速度は約20℃に極大を有し, それ以上の温度では急激に低下し, 天井温度が35-40℃付近に存在することがわかった ([1, 3-COD] 0・[SO2] 0=10mol2/l2 ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Mechanistic studies of plasma polymerization [PDF]

open access: yes, 1995
Plasma polymerization is a solventless method for depositing polymeric layers onto any substrate at room temperature. This technique comprises excitation, fragmentation, and polymerization of precursor molecules by an electrical discharge.
